In "Death of a Witch" by M.C. Beaton, Oscar Wilde's quote suggests that what we often label as wickedness is merely a construct created by those who consider themselves virtuous. It implies that 'good' individuals fabricate the concept of evil to explain their fascination with behaviors and people they deem undesirable. This perspective invites readers to question the nature of morality and the motivations behind labeling someone as wicked.

Wilde's insight serves as a commentary on societal norms and the human tendency to categorize others based on perceived moral standing. By framing wickedness as a myth, he encourages a deeper examination of our beliefs about good and evil, urging us to recognize that what one might see as immoral could be misunderstood or misrepresented. This theme resonates throughout Beaton's narrative, prompting reflection on the complexities of human behavior and the subjective nature of morality.
